Definitions
- the present invention relates to coinjection molding shooting pot apparatus and method that cools the shooting pot cylinder, thereby raising the viscosity of the melt therein, thus reducing leakage of the melt between the shooting pot cylinder wall and the shooting pot piston.
- Coinjection molding is typically used to mold multi-layered plastic packaging articles having a laminated wall structure. Each layer is typically passed through a different annular or circular passageway in a single nozzle structure and each layer is partially, sequentially, injected through the same mold gate.
- Some coinjection hot runner systems include shooting pots to meter material of one plastic resin so that each cavity of a multi-cavity mold receives an accurate dose of that resin in the molding cycle.
- a shooting pot piston within the shooting pot cylinder is actuated to discharge the resin into a hot runner manifold, which carries the resin to the coinjection nozzle and then into the mold cavity.
- U.S. Patent No. 4,717,324 to Schad discloses a coinjection hot runner assembly with shooting pots.
- the shooting pot chambers are an integral part of the hot runner manifold that is a heated component of the assembly.
- the shooting pot pistons that operate within the shooting pots must both slide and seal throughout their operating stroke. There is no disclosure of providing cooling or even lowering the temperature of the piston/shooting pot wall interface to reduce leakage.
- U.S. Patent No. 6,241,932 to Choi shows, in Figure 1 , a conventional two stage (preplasticizing) injection unit including a shooting pot and piston assembly. There is no disclosure of cooling the rear end of the shooting pot to minimize leakage or drooling.
- U.S. Patent No. 6,527,539 to Ujma teaches a shooting pot configuration of an injection molding machine. There is no disclosure of cooling the rear end of the shooting pot to minimize leakage or drooling.
- JP 8229984 discloses a shooting pot being loaded with two pellets that are pressurized and injected by the downward movement of a piston.
- the resin flows through a runner and fills a cavity to encapsulate an inserted lead frame. After solidification the mold is opened, the part removed and two more preheated pellets are loaded into the shooting pot.
- JP 60251633 A similar arrangement is disclosed in JP 60251633 .
- Resin tablets are loaded into a shooting pot and a piston is advanced to inject the resin into the runner below and then into the mold cavity to encapsulate an insert.
- the piston is temperature controlled by a fluid circuit so that the pellets can in turn be heated.
- a coinjection molding hot runner assembly configured to inject a melt through a coinjection nozzle having at least two melt channels ending at the same gate.
- the assembly comprises a hot runner manifold configured to supply the melt to the coinjection nozzle, a shooting pot cylinder configured to hold a metered shot of the melt, a shooting pot piston configured to discharge the melt from the shooting pot cylinder, a cooled manifold plate, and a heat sink disposed to contact an outer surface of the shooting pot cylinder and remove heat therefrom.
- a coinjection molding machine comprising a mold cavity, a coinjection nozzle having at least two melt channels ending at the same gate and configured to inject a melt into the mold cavity, and an assembly according to the first aspect of the present invention.
- the present invention provides for a method of cooling a coinjection mold shooting pot cylinder configured to inject a melt through a coinjection nozzle having a least two melt channels which end at the same gate, including the steps of: (i) charging a shooting pot cylinder with a melt; and (ii) removing heat from a portion of the shooting pot cylinder to increase the viscosity of melt therein to reduce melt leakage between the shooting pot cylinder and a shooting pot piston.
- a plastic resin coinjection molding machine has first and second shooting pots which respectively inject "A” and "C” resins through different coinjection nozzle melt channels into a mold cavity.
- first and second shooting pots which respectively inject "A" and "C” resins through different coinjection nozzle melt channels into a mold cavity.
- the present invention may find applicability in other injection molding applications as well, such as injection molding of metals, composites, etc.
- the below description will generally be limited to a discussion of a single shooting pot. However, it is to be understood that this description could apply to one or more of the shooting pots in a coinjection molding machine.
- the preferred embodiments of the present invention provide for cooling at least one shooting pot cylinder by use of a heat transfer sleeve adjacent the shooting pot cylinder.
- a heat transfer sleeve adjacent the shooting pot cylinder Such a configuration thus relies on melt viscosity to reduce leakage, controls the leakage thermally and not mechanically, and eliminates the need to use tight tolerances between the piston and cylinder.
- lowering the temperature in the top of the cylinder to precisely below the no-flow temperature of the resin can reduce the leakage significantly.
- the preferred embodiments also accommodate for heat expansion of the hot runner manifold as well as for that of the shooting pot by utilizing a spring for producing a loaded contact between the hot shooting pot and the cool plate through heat-sink sleeve.
- Figure 1 shows a portion of a coinjection hot runner assembly and mold comprising, in part, a first hot runner manifold 1, a second hot runner manifold 2, a nozzle housing 3, a cooled manifold plate 4, a shooting pot cylinder 5, a shooting pot piston 6, a heat-sink sleeve 7, a retaining ring 8, and a spring 9.
- the hot runner manifolds 1 and 2 are heated by heaters 10, and the manifold plate 4 is cooled by coolant flowing through cooling channels 11.
- the second melted plastic resin "C” is conveyed through second melt channels 12 in the heated second manifold 2 to the nozzle 3.
- a check valve assembly 13 is located in one end of the shooting pot cylinder 5 such that the incoming resin "C" from an inlet channel 14 is prevented from backflowing when the shooting pot piston 6 is advanced to inject the resin "C” into the mold cavity via the second hot runner melt channel 12 and the corresponding coinjection nozzle melt channel 26.
- the diametric sizing of the piston 6 in the shooting pot cylinder 5 is such that the piston 6 is able to slide without allowing a substantial amount of the resin contained therein from leaking past the piston sidewall. For example, a clearance of 10 to 20 microns allows the piston 6 to freely travel inside the shooting pot cylinder 5.
- the resin between the piston sidewall and the piston cylinder wall acts like a lubricant.
- the heat sink sleeve 7 By providing the heat sink sleeve 7 to cool the rearward end of the shooting pot cylinder 5, a more certain "sliding fit" configuration can be reliably provided.
- the heat sink sleeve 7 provides a path for heat to be thermally conducted from the rear end of the shooting pot cylinder 5 to the cooled manifold plate 4. This decreases the temperature of the resin "C", increasing its viscosity and preventing substantial leakage past the piston walls.
- the heat-sink sleeve 7 is tightly fitted (e.g., a 5 to 10 micron clearance fit) around the shooting pot cylinder 5 to be able to slide axially therealong and provide thermal expansion accommodation while keeping intimate contact with shooting pot cylinder for effective heat transfer.
- the heat sink sleeve 7 is retained in position on the shooting pot cylinder's external diameter by the retaining ring 8 and the spring 9 acting against a shoulder 16, which constantly urges the heat-sink sleeve 7 against its seat 19 in the manifold plate 4 to enhance the cooling.
- the thermal profile of the shooting pot cylinder is a function of the areas of contact between the heat sink sleeve 7 with the cooled manifold plate 4 and with the shooting pot cylinder itself.
- contact areas are optimized to produce (i) a temperature below the no-flow temperature of the resin "C” in the area of the piston inside the shooting pot cylinder 5 where these two components are permanently in contact, and (ii) a temperature equivalent to the molding temperature of the resin in the rest of the cylinder (metering area).
- the cooling of the shooting pot cylinder 5 can be fine tuned by judicious selection of the material(s) which comprise the heat sink sleeve 7, the longitudinal length and radial width (outside diameter minus inside diameter) of the sleeve, the shape of the sleeve (the inner surface thereof may be profiled with sinusoidal or stepped shapes), the closeness and extent of the contact between the sleeve and the cooled manifold plate and the cylinder wall, etc.
- the heat sink sleeve 7 is made of tool steel, has a longitudinal length of 6-12 mm, an inside diameter of 10 mm, and an outside diameter of 20 mm.
- the area that the sleeve 7 contacts the cooled manifold plate 4 is the same area as it contacts the outside diameter of the cylinder wall.
- the sleeve 7 contacts the cylinder wall 5 throughout the entire inner surface of the sleeve.
- the sleeve 7 can be provided with cooling fins, cooling channels with coolant flowing therein, or other cooling aids, etc.
- the shooting pot cylinder 5 is charged with resin "C" by an injection unit (not shown) feeding the resin through the inlet channel 14, past the check valve 13.
- This infeeding resin causes the shooting pot piston 6 to move away from the check valve 13, extending outwardly from the shooting pot cylinder 5.
- the shooting pot piston 6 is stopped by its actuation rod (not shown) at a predetermined position, this limits the shot size of the resin in the shooting pot cylinder 5 to a volume created by the piston's rearward movement.
- the shooting pot piston 6 is moved forward by the actuating rod acting on the exposed end 18 of piston 6.
- the forward movement of the piston 6 displaces the resin "C" from the shooting pot cylinder 5 via the channel 12 and the nozzle melt channel 26 and into the mold cavity through the mold gate.
- the check valve 13 prevents 7 backflowing of the resin into the inlet channel 14.
- the heat sink sleeve 7 extracts sufficient heat to reduce the resin temperature and increase its viscosity to a point where leakage past the piston wall is substantially prevented.
- a shooting pot cylinder 20 containing a shooting pot piston 21 is surrounded by a heat-sink sleeve 24 having a bore that has a sliding fit to the outer diameter of the shooting pot cylinder 20.
- the sleeve 24 is located in a recessed seat in a cooled manifold plate 25 and held in place by a retainer ring 22 and a spring washer 23 that constantly urges the sleeve 24 against its seat in the manifold plate, thereby ensuring good contact for thermally conducting heat from the shooting pot cylinder wall to the plate while allowing the shooting pot cylinder to thermally expand and slide within the bore of the heat-sink sleeve 24.
- This alternate embodiment does not require the shoulder 16 of the Figure 1 configuration and thereby makes a slightly less costly component.
